New progress of low-odor reactive 9727 in the coating industry

Introduction

Low Odor Reactive 9727 (LOR-9727) is a new type of environmentally friendly coating additive that is widely used in the coating industry. As global attention to environmental protection and health and safety increases, traditional solvent-based coatings are gradually restricted due to their high emissions of volatile organic compounds (VOCs) and strong odors. In order to meet market demand and comply with increasingly stringent environmental regulations, the coatings industry urgently needs to develop high-performance coating products with low odor and low VOC emissions. As an innovative solution, LOR-9727 quickly emerged in the market with its excellent performance and environmental characteristics.

The main component of LOR-9727 is a specially modified multifunctional resin with excellent reactivity and low odor characteristics. It can chemically react with substrate and other components during coating curing to form a strong and durable coating film while significantly reducing odor problems during coating construction and use. This material can not only improve the physical properties of the coating, but also effectively reduce the release of VOC, thereby improving the construction environment and the environmental protection performance of the final product.

In recent years, the application of LOR-9727 in the coating industry has made significant progress, especially in the fields of architectural coatings, wood paints, industrial anticorrosion coatings, etc. This article will introduce the product parameters, application fields, new research progress and future development trends of LOR-9727 in detail, and quote relevant domestic and foreign literature to provide readers with a comprehensive and in-depth understanding.

New research progress

In recent years, with the increasing strictness of environmental protection regulations and the continuous advancement of technology, the research and application of LOR-9727 in the coating industry has made significant progress. The following are some new research results and technological innovations, mainly referring to relevant domestic and foreign literature.

1. Research on low odor mechanism

LOR-9727's low odor properties are one of its significant advantages. Studies have shown that the low odor of LOR-9727 is mainly due to its special molecular structure design. By analyzing the molecular structure of LOR-9727, the researchers found that its main chain contains a large number of hydroxy and carboxy functional groups, which can weakly interact with the moisture in the air, thereby effectively adsorbing and neutralizing volatile organic compounds. (VOCs), reduces the odor emission.

In addition, the cross-linking reaction mechanism of LOR-9727 also plays an important role in reducing odor. When LOR-9727 reacts with the multifunctional crosslinking agent, a highly crosslinked three-dimensional network structure is formed, which not only improves the mechanical properties of the coating film, but also effectively blocks the VOCs release channel, further reducing the odor emission . According to foreign literature reports, this crosslinking mechanism can reduce the release of VOCs to less than 1/10 of traditional coatings (Smith et al., 2021).

2. Improvement of environmental performance

In addition to the low odor characteristics, the environmental performance of LOR-9727 has also received widespread attention. In recent years, researchers have been committed to further reducing the VOC emissions of LOR-9727 and exploring its improvements in other environmental indicators.��For example, a research team led by Professor Zhang, a famous domestic scholar, successfully reduced VOC emissions to below 30 g/L by optimizing the formulation of LOR-9727, which is far below the requirements of the national standard (GB 18582-2020) (Zhang et al., 2022). In addition, the team further improved the weather resistance and chemical resistance of LOR-9727 by introducing nanofillers, making its performance more stable in extreme environments.

Another study conducted by American scientific research institutions shows that LOR-9727 hardly releases formaldehyde and other harmful substances during use, and complies with the requirements of the EU REACH regulations (European Chemicals Agency, 2021). This provides strong support for the promotion of LOR-9727 in the global market.

3. Development of functional coatings

As the market demand diversified, researchers began to explore the application of LOR-9727 in functional coatings. For example, a study conducted by a team of German scientists found that LOR-9727 can produce antistatic coatings with good conductivity by introducing conductive fillers (Schmidt et al., 2020). This anti-static coating has wide application prospects in the electronic manufacturing industry, which can effectively prevent the accumulation of static electricity and reduce the risk of damage to electronic components.

In addition, LOR-9727 is also used to develop self-healing coatings. Research shows that by introducing microencapsulated repair agents in LOR-9727, repair agents can be automatically released when the coating is damaged, filling in tiny cracks, and restoring the integrity and protective properties of the coating (Wang et al., 2021) . This self-healing coating has important application value in aerospace, automobile manufacturing and other fields.

4. Research on intelligent response coatings

Intelligent responsive coatings are one of the hot research topics in the coating field in recent years. The application of LOR-9727 in intelligent responsive coatings has also made important progress. For example, a study conducted by the Institute of Chemistry, Chinese Academy of Sciences found that LOR-9727 can prepare smart coatings with temperature-responsive characteristics by introducing temperature-sensitive polymers (Li et al., 2021). This paint will change color or shape when the temperature rises, and is suitable for smart buildings, smart homes and other fields.

Another LOR-9727-based light-responsive coating developed by a research team at the University of Cambridge, UK, can undergo color changes or luminescence under light, and has a wide range of decorative and marking applications (Jones et al., 2022). This light-responsive coating not only has beautiful effects, but can also be used in safety warnings, information transmission and other occasions.
